Fig. 2 is a side elevation thereof.

Fig 3 a sectional detail on. line 3-3 of llig. l...

l is 'a sectional detail on line 4 -l of Fig. l 7

ll ig. ii is a sectional detail on line -5 suitahle manner and in any convenient posisaid bed plate is provided with forwardly extending arms 2 as clearly shown in. l igsn 1 and L. Secured upon the arln extensions 2, are bearing blocks 3,- in which a shaft 41:, is jo'urualed, provided with a large gear Also secured upon one of said arm. extensions 2 is another hearing tion for use, and

block: 6, through which a shaft 7, is jour- 'nalcd provided on one end with a driving pulley ll, and on the other end Vlflilh a pinion 9, meshing with the large gear 5.

Attached upon the bed plate 1, as shown clearly in Fig. 8, are outer guide bars 10, and inner guide bars ll, and slidable therehetween is a carriage consisting of long slide bars 12, each formed With teeth along'a por rear end is provided with an upright 14L, rigidly secured thereto in any suitable manner.

Recessed into the respective uprights 14, and slidably associated'wi'th a block 15, shown lli ldfltflill in hlg. 7, and each provided with a pin 16 which extends and each at its forming a rack 13,

each thereof is line 7 7 through a slot 17 in the side wall of its upright 14. Secured to said respective blocks 15, and extending across the machine is a long flat thin feeding plate 18. A coil spring 19, is seated in each of the recessed uprights 14, as shown in detail in Fig. 7, bearing behind the blocks 15, so that said feeding plate 18; is normally thrust forwardly with each of the pins 16, disposed in the forward end of each of the slots 17.

Mounted transversely of the machine at one end thereof is an upright cross-piece 20, slotted to receive engaged therein a plurality of forwardly extending parallel bars 21, and with a clamping bar 22, slotted and fitting over said bars 21, to hold the same secure upon the cross-piece 20. As clearly shown in Fig. 5, the forward ends of each of said bars 21, are fork-shaped as denoted by the reference numeral 23, and extend downwardly and fit over another cross-piece 24, secured transversely on the frame bed 1. Saidfork-portions of the bars 21, fit over a transversely extending shaft 25, which at its ends is journaled in bearing blocks 26, mounted one on each side of the machine. Attached between said bearing blocks 26, is a cross-member 27, and secured thereto by clamping bars 28 and 29, on each side of said cross-piece are fork-shaped plates 30, which extefid downwardly closely to and in register with the edges of the bars 21. Journaled transversely on the machine in bearing blocks 26, is another shaft 31, above and parallel to the shaft 25, and extending through the fork-shaped plates 30. Said shafts 25 and 31, are provided on their outer ends with intermeshin g pinions 32 and 33, respectively, and as shown in Fig. 2, wide idler pinions 34, are mounted on each of the bearing blocks 26, and each meshes with one of the pinions 32, and with a rack 13. Mounted upon each of the respective shafts 25 and 31, are aseries of toothed segment folding or creasing rollegs 25, and 31*, respectively, the toothed portions of which are adapted to mesh when the shafts are intermeshing pinions.

Slidably mounted between the inner guide bars 11, as shown in Figs. 1 and 5, is a flat plate 35, which extends transversely of the machine, and atits forward edge is provided with an upright portion 36. Integral with the upright portion-36, are a plurality of rearwardly extending arms 37 and pivoted thereon. as clearly shown in Figs. 1 and 5, are forwardly extending arms 38. The forward upper portion of the,face of the upright portion 36, is cored out, and disposed therein is a hQfliSlDg GOll 39, Shawn in Fig. 5, and attached thereover is of "T-section. Secured on the under portion rotated by their a heating plate 40,

rights 42, are secured upon the bed frame 1, one at each side and one centrally thereof, as shown in Fig. 1, and secured rigidly therein is a transversely extending cross-bar 43, beneath which the rear end of each of the arms 38, is normally disposed. As shown clearly in the detail view in Fig. 6, each of said arms 38, is normally impelled upwardly in the position shown in Fig. 5, by coiled springs 44, seated in recesses provided therefor in the rearwardly extending arms 37.

Secured upon the outer end of the shaft 4, are cam wheels 45, each having a cam groove 46, therein. The ends of the respective slide bars 12, as clearly shown in Figs. 1 and 2, are provided with rollers which fit into the respective cam grooves 46, whereby, due to rotation of the cam wheels 45, a certain oscillation or reciprocating movement of said bars 12, is caused to take place. Also mounted upon said shaft 4, are cam wheels 47, each provided with a cam groove 48, as shown in- Fig. 5, and rearwardly extending arms 49, integral with the plate. 35, are provided with rollers which engage in said am grooves for a certain. operative movement of the plate 3536. v

Fig. 8 shows in plan view a strip of paper denoted by the reference numeral 50, which is transversely perforated, with indicatingcharacte'rs' marked upon each perforated division. It is desirable to crinkle or fold said strip of paper into plaited form with the plaits extending longitudinally, that is, at right angles to the lines of perforation there in, so that the strip when completed will have the form shown in Fig. 10. When the sheet is first thrust between the creasing or folding rolls, it is creased longitudinally as shown in the end View of the strip illustrated in Fig. 9. The finally folded plaited strip is shown in Fig. 10.

Stops 51, are provided on the respective bearing blocks 26, and are 50 disposed that, when the plate 18, has been brought in position to hold the strip against the heating plate 40, a further forward movement of front of the forwardor feeding edge of the flat plate 18. As the cam wheels 45, rotate, the cam grooves 46, therein, serve to draw the slide bars 12, inwardly thereby sliding the flat plate 18; forwardly over the bars 21, and feeding the paper strip 50, beneath the depending fork-plates 30, and into the field of operation of the segment toothed folder rolls 25 and 31". I That is, the plate 18, feeds the strip forwardly sufficiently to cause said 'rollsto engage with the strip, inasmuch as the rolls have rotated into position for the teeth to engage with the strip, and thereby continue. the feeding operation of the strip at the same time creasing the strip longitudinally. This driving motion is imparted to the rolls due to the fact that the arms'12,

which slide the plate 18, inwardly are cash provided with the rack teeth 13, which drive the respective idlergears 3%, on each side of the machine, and which in turn drive the intermeshing pinions 32 and The operation of the parts is so timed that the toothed portions of said rolls and 31% have passed out of mesh at the time that the plate 18, is introduced therebetwcen toeontactthe rear edge of the creased paper,

strip and contii'me the feeding movement thereof into and against the heating plate 4.0. Said plate 18, serves to press the creased strip against the heating; plate thereby foldinp, the creased strip from the condition shown in Fig. 9, to that shown in Fig. 10. The opposite portions f the cam grooves L6, to that shown in Fig. 2, are then in engagement with the roller-son the ends of the slide bars 12, affording a rest period, and the plate is held against the creased 1 strip. Said plate is held against the folded strip under spring pressure, owing to the fact that the plate 18, is carried on the blocks 15, shown in detail in Fig. 7, which are spring impelled from the uprights 14, secured to the slide bars 12.

The stops 51, secured on the outer-,ends of the hearing blocks 26, are so disposed that said blocks 15, on which the plate .18,

ismounted, cannot travel beyond a predetermined distance when the compressive effect onthe springs 19, is released, due to the retraction of the heating plate 40, as described in the following.

After the creased and folded paper strips have been held for time gainst the heated plate so, the cam wheels 47, have rotated sufficiently so that the cam groove 48,

therein cause a retraction of the plate 35-36, on which the heating plate is meant ed, and at the same time the pivoted arms 38, carried thereby are thrust beneath the stationary cross-piece 43, shown in Fig. 5,

causing said arms to be depressed as shown in Fig. 6, thereby actuating the bar 41,

across the heating plate 40, to eject the folded and creased strip therefrom, and the strip is discharged through the slot 52, in the bed plate. Of course, immediately thereafter, the cam wheels 45, serve to return the feed plate 18, back to initial position, and similarly the cam wheels 47, operate to return the plate Elli-36, to normal,

ready for another folding operation.

I am aware that val-1011s detalls of construction may be varied through a wlde range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted othen wise than necessitated by the'prior art.
